Added compatibility with CMake 4

[xvitaly]

CMake 4 removes support for all CMake versions prior to 3.5:

CMake Error at CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 3.5 has been removed from CMake.
  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.
  Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.

This PR adds compatibility with CMake 4.
